Description

This product is 100% Made in the USA! Our gas tubes, gas blocks and even roll pins are all proudly manufactured in the US. All Complete uppers are headspaced prior to shipping and test fired.

The BKF AR15 M4 MOD-1 Rail M-LOK series provides an alternative aesthetically progressive design that is lightweight with our 7075-T6 Steel barrel nut and attach method. The innovative attachment of the rail and the barrel nut provides a solid lockup, a seamless, strong joint that requires no timed alignment to the barrel nut itself. All BKF M4 MOD-1 rails (and receivers for that matter) are designed with pocketed cutouts to further minimize weight. In addition, BKF M4 MOD-1 rails offer QD mounting at the rear 3,6 and 9 O’clock of the handguard.
